Procedure
A mixture of 3.7 g of 5-(2-hydroxy-3-butylthiopropoxy)chromone-2-carboxylic acid monohydrate and 10 ml of N sodium hydroxide is stirred for 10 minutes and the precipitate which forms is filtered, washed with a little acetone and dried. Thus, 3.5 g sodium 5-(2-hydroxy-3-butylthiopropoxy)chromone-2-carboxylate is obtained.
